Engine nr 2 (rear) has revolving (around horizonytal axis) intake, capable to switch from closed to open position during flight.The nr 2 engine has a seemingly very small air inlet on the top of the fuselage. One would suspect it would be running at a lower capacity than the other two. Has any-one more info on this small intake?
That is relevant to my interests. I'm made dubious, however, due to the high shipping cost. Gah.
